Spectre (security vulnerability): History, Mitigation & Mechanism

Spectre is a class of speculative execution CPU vulnerabilities that involve side-channel attacks, first discovered in 2017. There are multiple variants that affect modern microprocessors capable of performing branch prediction and other forms of speculative execution. On most processors, the speculative execution resulting from a branch misprediction…
